Solution: Nested Loop With Multiplication (Intermediate)

This review provides a detailed analysis of the different ways to solve the Nested Loop with Multiplication (Intermediate) challenge.

We'll cover the following...

Solution

Node.js
// Initializations
const n = 10;
const pie = 3.14;
let sum = 0;
var j = 1;
for (var i = 1; i < n; i += 3) {
    console.log(pie);
    while (j < n) {
        sum = sum + 1;
        j *= 3;
    }
    j = 1;
}
console.log(sum)

  • The outer loop index i goes: 1,4,7,10,⋯ ,n1,4,7,10,\cdots,n. That means that the outer loop has n3\frac{n}{3} ...
